CHIMN EY.

Application filed August 2, 1918.

To all whom t may concern:

Be it known that l, Rento S. BAssr'r'r, a citizen of the United States, residing at Champaign, in the county of Champaign and State of Illinois, have invented certain new and useful Improvements in Chimneys, of which the following' is a specification.

This invention relates to chimneys and more particularly to portable chimneys adapted for use in connection with portable buildings, and more especially portable buildings of the type shown and described by me in my copending application, Serial No. 218, 960, filed Februarv 25, 1918.

One object of the present invention is to provide a. chimney of the type described which may be readily and quickly positioned in a portable building after the same has been erected and one which may be bodily removed therefrom, when it is desired to disassemble the building without injury to either the chimney or the building.

Another object of the invention resides in the provision of portable chimney which shall be provided with means adapted to serve as a .f'entilating passage for the conduction of air from within the building to the exterior thereof.

A further object is to provide a portable chimney designed to be supported in any suitable manner a substantial distance above the floor of the building to which it is attached, whereby the corner spacev ordinarily occupied by ehimneysof the type now eXtensively used may be utilized for storage or other purposes, or may, if desired, be left entirely unobstructed.

Other objects and advantages will be apparent from the following description taken in connect-ion with the accompanying drawings wherein the preferred embodiment of the invention is illustrated.

Figure 1 is a sectional view taken through a portion of a portable building sh owing the chimney mounted in position;

Fig. 2 is a longitudinally vertical sectional view taken through the chimney and its support;

Fig. 3 is a bottom plan view of the chimney, and y Fig. 4 is a detail sectional view of the ventilating plate.

Referring more in detail to the drawings, the floor of the building is illustrated at 10, the ceiling thereof at 11, and the roof at 12.

serial no. 247,901.

1st designates a partition mounted between the ceiling and floor of the building for the purpose of dividing the space between the outer walls thereof into rooms A and B, one on each side of said partition.

Mounted preferably in the corner of the room fr and standing' on the floor of the building is a suitable closet or other storage chamber 15, said closet comprising corner uprights 16, side and back panels 1T, and a door 1S preferably hinged along one of its longitudinal edges as at 19 and provided with a latch 20 or other suitable means for maintaining said door in its closed position. The closet is further provided with a bottom plate 21 and a op plate Thus it will be noted that a closet inclosed on all sides is provided in which various household articles may be conveniently stored. The closet has been found particularly advantageous, in view of its tall shallow design, for the storage of a mop, broom or the like.

The corner posts 16 of the closet, it will be ,noted from Fig. 2 of the drawings, extend above the top plate 22 thereof, as illustrated at 23, and below the bottom plate 21 as illustrated at 24E. The portions 2e form the supporting legs of the closet whereas the portions 23, which project above the top plate 22 of the closet, provide a support for the chimney which is designated as a whole as 25 and which, as will be noted, rests upon the upper ends of the corner posts 16, the space between the bottom of the chimney and the top plate of the closet being preferably left entirely open as shown in Fig. 1 for purposes hereinafter described.

rThe chimney comprises a base plate or ventilating member 26 which rests on the upper ends of the corner posts 16 of the closet and is supported directly thereby, said Ventilating plate being preferably of rectangular design, the said corner posts 16 being designed to support said plate by engagement therewith at each of the four corners thereof. This plate 26 is preferably provided with an upstanding flange 27 extending around the plate adjacent the outer edge thereof and a second upstanding Harige 28 extending around the plate but offset slightly inwardly from the flange 27, it being preferred to form the two flanges integral with the plate. The Hue of the chimney is illustrated at 29, the same being also preferably rectangular in crosssection and designed to rest on the base plate 2G and to engage the flange 28 thereof, fitting snugly down around the outer face of said flange on all four sides, as will bemore readily understood by referring to Fig. 2 .ofthe drawings. The outei wall of the chimney is illustrated at 30 and is also adapted to seat upon the base plate 26, the four sides being spaced equal distances from the four sides of the flue and securely held in posi- Y tion by means of bolts 3l or other suitable fastening means which are designed to extend through the upstanding flange 27 of the base plate 26 and the adjacent portion of the outer wall of said chimney, said bolts being positioned in such wise that the heads thereof engage the flange 27, thus leaving the outer ends of said bolts free to be en gaged by suitable nuts. lt is preferred to position the bolts in this manner in order that the nuts thereof may be more readily accessible.

From the foregoing it will be noted that the outer wall 8O of the chimney is held rigidly in position by means of the Hangs 27 and the bolts 3l, while the flue of the chimney is held spaced from the outer wall 8O thereof by means of the frange 28. lt will thus be seen that an air space is provided between the flue 29 of the chimney and the outer wall thereof, as illustrated at 32 in the drawings. In other words, the flue is out of contact with the outer wall of the chimney throughout its entire height. lThis provides a substantial protection against fire by reason lof the fact that the outer wall, due to the air space between it and the flue, is effectively prevented from becoming overheated by the gases orother products of combustion passing through said flue. The chimney is provided with the usual cone cap 33 which is supported thereabove by means of suitableV metal vstraps or standards 34. i A further object of the invention, as has been pointed out, is to provide means whereby the room of the building into which the lower portion of the chimney extends may be effectively ventilated and with this in view the base plate 26 of the chimney is provided with a plurality of apertures 35 which extend therethrough to provider a communication between the air space 32 and the room into which the chimney ex" tends. As above pointed out, the air space 32 isv continuous from the base plate 26V upwardly throughout the entire height of the chimney, said air space opening into the atmosphere around the top edge of the chimney. This, in view of the fact that the space between the base plate 26 and the top plate 22 of the closet is entirelyV open, as previously described, affords means whereby air from the room A is drawn up through the apertures 35 and the air space 32 between the flue and the outer wall of the tion.

chimney from whence it is passed out into the atmosphere. lt will be readily apparent that the air space between the walls of the chimney will Vat all times be heated to some extent during the passage of products of combustion through the flue and that by reason of this a positive upward draft is established which will act to draw air from the room A and to cause it to be passed off into the exterior atmosphere thereby providing Ventilating means for the building and particularly for the room A into which the chimney extends. Y

lt is preferred to provide the chimney with two stove-pipe openings 36 on opposite sides thereof. @ne of these openings isV provided with a suitable annular collar 37 having its inner and outer ends flanged over against the adjacent surface of the flue and outer wall of the chimney respectively as illustrated at 38, this opening being designed for connection with the stovepipe leading from a stove (not shownj in room The other stove-pipe opening 35 is preferably provided with a thimble 39 flanged over on its inner end against the adjacent wall of the flue 29 as shown at 40 and also flanged intermediate its ends against the adjacent surface of the outer wall of the chimney 30 as illustrated at 4l. The thimble 39 extends, as will be noted, beyond `the outer wall 30 of the chimneythe same being designed to extend through the partition wall l4 of the building wherebythe same may be connected to the stove-pipe leading from a stove (notshown) in room B. The portion of the thimble which extends through the partition wall is preferably provided with a protecting lcollar 43 having inner and outer rims 44 separated by suitable lattice worlr 45 for the purpose of providing sufficient radiating area to Yprevent the heat of the stove pipe being conducted to the adjacent wall of theparti- In this manner stoves in different rooms of the building maybe connected to the chimney, the lower portion of which extendsinto only one of said rooms. It is, of course, obvious that other stove-pipe connectionsmay be provided whereby the chimneymay be connected with stoves positioned Vin other rooms of the' building, if desired.

While the outer `wall 30 and the flue 29 of the chimney are held rigidly in position by he upstanding flanges and securing means above described, it will be noted 'from the preceding that the flanged Vcollar 37 and the fianged thimble 39 provide additional means for maintaining the inner and outerwalls of the chimney rigidly secured together in their spaced relationship. 'A 1 While the chimney described herein has been'illustrated as supported upon the corner posts of a closet, it is,'of course, obvious that the same may, if desired,'be supported on brackets or in any other manner which will leave the space below the chimney unobstructed, In other words, any suitable supporting means may be provided to support the chimney in its proper position.

The portion of the chimney adjacent the roof of the building is preferably provided with a suitable collar d6 provided with an annular flange 47 adapted to rest down upon the upper surface ofthe roof. After the chimney has been positioned, it is preferred to cover this flange with the roofing material substantially as shown in Fig. l. In this manner the opening cut in the roof to permit of the chimney passing therethrough is completely covered and leakage at this point thereby prevented.

From the above, it will be apparent that a chimney has been provided which may be readily and quickly placed in position in a completed building, one which is designed to be supported a substantial distance above the door of the building, whereby the space ordinarily occupied by chimneys of the type now extensively used may be used to advantage, and further that a chimney has been provided which embodies means for ventilating the building to which it is attached, and one which is bodily removable from the building when it is desired to dis assemble the same.

It is obvious that many changes and modifications may be made in the construction herein illustrated and described without departing from the spirit of the invention and it is not, therefore, desired to limit the invention except where limitations appear in the appended claims.

lVhat I claim is:

l. In a portable building, a floor, a cabinet thereon providing a storage compartment, a chimney mounted upon said cabinet and extending upwardly therefrom through the roof of said building, said chimney being movable bodily into and out of position on said cabinet, whereby said chimney may be removed from said building without injury to either.

2. A chimney of the type described comprising an apertured base plate, a flue and an outer wall mounted thereon, upstanding flanges on said plate adapted to maintain said Hue and said outer wall spaced apart, whereby a chamber is provided between said flue and said outer wall, said chamber opening exteriorly of said chimney at one end through said apertured plate, and a lateral connection whereby the pipe of the stove or other heating apparatus may be connected to said flue, the passage of combustion products through said flue tending to produce a forced draft of air through said chamber.

3. The combination with a portable building comprising a floor, a ceiling and a roof, of a portable cabinet therein resting on said floor and extending nearly to said ceilinfr, a double wall metallic chimney passing through alined openings in said ceiling and said roof and resting on said cabinet, and a lateral inlet to said chimney arranged between the top of said cabinet and said ceiling.

In testimony whereof, l have subscribed my name.
